This study reports the preparation and characterization of Polybutylene Succinate (PBS)-Polycaprolactone (PCL) melt blends (10-40 wt.% PCL) in the presence of a compatibilizer, in order to explore their potential use as a biomaterial. The thermal transitions, as well as the crystallinity of the polymer blends were analyzed by Differential Scanning Calorimetry, the thermomechanical properties were analyzed via Dynamic Mechanical Analysis and phase morphologies were characterized by Scanning Electron Microscopy. Degradation profiles of the blends were analyzed in PBS buffer solution at pH 7.4 at 37 degrees C via pH measurements. Cytotoxicity of the PBS/PCL films were tested by MTS assay.


Polystyrene-organoclay nanocomposites prepared by melt intercalation, in situ, and Masterbatch methods
Yılmazer, Ülkü; Ozden, G (Wiley, 2006-06-01)
In this study, polystyrene (PS)/montmorillonite nanocomposites were prepared by melt intercalation, in situ polymerization, and masterbatch methods. In the masterbatch method, as the first step, a high clay content composite of PS-organoclay (masterbatch) was prepared by in situ polymerization, and then the prepared masterbatch was diluted to desired compositions with commercial PS in a twin-screw extruder. The structure and mechanical properties of the nanocomposites were examined. X-ray diffraction (XRD) ...

The effect of temperature and soluble solids on nonenzymatic browning in clarified and concentrated apple juice was analyzed by response surface methodology. Color development at 20, 40 and 60 Brix and temperatures ranging from 70-90C were compared over a time range of 30-180 min. The browning reaction was found to be dependent on soluble solid content as well as on the reaction conditions such as temperature and time. The model combines the effect of temperature, soluble solids content and time on color ch...
Trimethylene Carbonate and epsilon-Caprolactone Based (co)Polymer Networks: Mechanical Properties and Enzymatic Degradation
Bat, Erhan; Harmsen, Martin C.; van Luyn, Marja J. A.; Zhang, Zheng; Grijpma, Dirk W.; Feijen, Jan (American Chemical Society (ACS), 2008-11-01)
High molecular weight trimethylene carbonate (TMC) and epsilon-caprolactone (CL) (co)polymers were synthesized. Melt pressed (co)polymer films were cross-linked by gamma irradiation (25 kGy or 50 kGy) in vacuum, yielding gel fractions of up to 70%. The effects of copolymer composition and irradiation dose on the cytotoxicity, surface properties, degradation behavior, and mechanical and thermal properties of these (co)polymers and networks were investigated. Upon incubation with cell culture medium containin...

Block and random copolymers having 3-methyl thienylmethacrylate and 6-(4-cyanobiphenyl-4'-oxy) hexyl acrylate moieties were utilized as precursor polymers in this study. Electrochemical copolymerizations were performed in the presence of thiophene or pyrrole in acetonitrile-tetrabutylammonium tetrafluoroborate (TBAFB) at constant potential. The characterizations were performed by cyclic voltammetry (CV), fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermal gravime...
Viscoelastic properties of reactive and non-reactive blends of ethylene-methyl acrylate copolymers with styrene-maleic anhydride copolymer
Bayram, G; Yılmazer, Ülkü; Xanthos, M (Wiley, 2001-02-01)
The effects of compatibilizing reactions on the viscoelastic properties and morphology of ethylene-methyl acrylate copolymers were studied. Potentially reactive blends of styrene-maleic anhydride copolymer (SMAH) and a terpolymer of ethylene/methyl acrylate/glycidyl methacrylate (E-MA-GMA) were compared with a nonreactive blend of SMAH and an ethylene/methyl acrylate (E-MA) copolymer with similar rheological properties. Melt mixing was carried out in a batch mixer and in a co-rotating twin screw extruder. T...
